摘要：
The kinetics of the oxidation of ethylbenzene, limonene, and methyl linoleate containing mercaptoethanol additives were studied, as well as cis-trans-isomerization of the double bonds in methyl linoleate. Mercaptoethanol (RSH) additives were found to accelerate the oxidation of hydrocarbons and methyl linoleate due to the reaction of RSH with hydroperoxides (primary oxidation products) resulting in a low yield of free radicals. The cis-trans-isomerization catalyzed by thiyl radicals produced in the exchange radical reactions with RSH decelerates in the presence of oxygen.
